DETAILED DESCRIPTION OF THE EMBODIMENTS

The present invention discloses a connecting structure of a zipper. The basic principle and structure utilized by the connecting structure of the zipper are known by those skilled in the art, and thus will not be explained in the following description. The accompanying drawings are a schematic view of the feature of the structure in accordance with the present invention, and thus may not be shown with actual shape and scale.

The First Embodiment

Refer to FIGS. 3 and 4, which illustrate a schematic view of the first embodiment of the connecting structure of the zipper in accordance with the present invention. The connecting structure includes a pair of zipper belts 20. An inner side of the pair of zipper belts 20 has a first edge 21, and an outer side thereof has a second edge 22. The first edge 21 is each provided with a pair of zipper teeth 23 corresponding to each other. A zipper head 24 is provided on the pair of zipper teeth 23. The zipper head 24 is responsible for closing and separating the pair of zipper teeth 23. The second edge 22 is each connected to a body 25 of a connecting element. The present invention is characterized in that when the second edge 22 of the pair of zipper belts 20 is folded backward, the body 25 of the connecting element is covered and connected to form a first connecting portion 26. The body 25 of the connecting element is then folded backward to form a second connecting portion 27.

In a preferred embodiment, as shown in the circle in FIG. 4, the first connecting portion 26 and the second connecting portion 27 are sewed twice. As shown in FIG. 4, the first connecting portion 26 is formed at the first seam such that the second edge 22 is seamed with the body 25 of the connecting element. Then the body 25 of the connecting body is folded backward so as to form the second connecting portion 27 such that the connecting element is on top while the zipper belts are on bottom, as shown in FIG. 4. Sewing can also be replaced or combined with glue for connecting purpose (not shown). This type of zipper may include all kinds of zippers, such as nylon, plastic steel, copper and aluminum zipper as well as sealing zipper and any other zippers. It is to be noted that the shape of the above-mentioned zipper head 24 and zipper teeth 23 is not restricted to any specific kind. Any shape of zipper, zipper teeth, zipper groove or zipper head and any other zipping structure without a zipper head used for controlling the open and close thereof are all included within the scope of the present invention and may be substituted in the embodiment of the present invention achieving the same effect.

The Second Embodiment

Refer to FIG. 5, which illustrates a schematic view of the second embodiment of the connecting structure of the zipper. The connecting structure includes a pair of zipper belts 20. An inner side of the pair of zipper belts 20 has a first edge 21, and an outer side thereof has a second edge 22. The first edge 21 is each provided with a pair of zipper teeth 23 corresponding to each other. A zipper head 24 is provided on the pair of zipper teeth 23. The zipper head 24 is responsible for closing and separating the pair of zipper teeth 23. The second edge 22 is each connected to a body 25 of a connecting element. The present invention is characterized in that when the second edge 22 of the pair of zipper belt 20 is folded backward, the body 25 of the connecting element is covered and connected to form a first connecting portion 26. The second edge 22 of the zipper belts is then folded with the first connecting portion 26 to form a second connecting portion 27.

In a preferred embodiment, as shown in the circle in FIG. 5, the first connecting portion 26 and the second connecting portion 27 are sewed twice. The first connecting portion 26 is formed at the first seam such that the second edge 22 is seamed with the body 25 of the connecting element. Then, the second edge 22 of the zipper belts is folded backward to for the second connecting portion 27 such that the zipper belts are on top while the connecting element is on bottom. Sewing can also be replaced or combined with glue for connecting purpose (not shown). This type of zipper may include all kinds of zippers, such as nylon, plastic steel, copper and aluminum zipper as well as sealing zipper and any other zippers. It is to be noted that the shape of the above-mentioned zipper head 24 and zipper teeth 23 is not restricted to any specific kind. Any shape of zipper, zipper teeth, zipper groove or zipper head and any other clamping structure without a zipper head used for controlling the open and close thereof are all included within the scope of the present invention and may be substituted in the embodiment of the present invention achieving the same effect.
